DUMP CAR.

application led May 27, 1922.

To all wilma 'it may concern.'

Be it known that l.. ARGYLE CAMPBELL, a gsitizen of the United States, residing at Chicago, in the county of Cook and otate of illinois, have invented a certain new and useful Improvement in Dump Cars, of which the following is a full, Clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements i dump cars.

One object of the invention is to provide a strong, durable and relatively inexpensive locking mechanism for gravity drop doors of a dump car and more particularly for drop doors of dump cars of the gondola type.

Another object of the invention is to provide a` relatively inexpensive combined door brace and hinge strap which may be readily applied to new or old cars.

A. further object of the invention is to provide, in a dump car, a novel and efficient combined floor brace and sealing arrangenient at .the joint between the car floor and the hinge edge. of the door in order to prevent any of the load getting in the crack and preventing full closure of the door thereafter.

In the drawings forming a part of this specilicat-ion, Figure l is a side elevation of a portion of a gondolacar showing my improvements in connection therewith. F ignre 2 is a vertical transverse sectional view corresponding substantially to the section line 2-2 of Figure 1. Figure 3 is a part top plan and part horizontal section of the car shown in Figures 1 and 2 and illiisti'ating more particularly the floor door ai'- rangeinciit and certain details of the side wall construction. Figure l is an end elevation, upon a larger scale, of one of the door braces. Figure 5 is a view similar to Figure 3 illustrating another embodiment ofthe invention. Figure 6 is a transverse vertical sectional View of the car shown in .Figure 5, the section corresponding to the line 6-6 of Figure 5. And Figures 7 and 8 are detail vertical sectional views corresponding to the section line of Figure 5, Figure 7 looking in the direction of the arrows 7-7 and Figure 8 looking in the direction of the arrows 8 8.

sei-iai No. 564,050.

Referring first to the construction illustrated in Figures l to 1l, inclusive, the gondola car therein shown is provided with channel center sills l0, diaphragms or needle beams l1, 12, wooden side Wall 13, pressed side stakes 14, pressed diagonal braces 15, angle side sill 16, longitudinal center floor plank 17, longitudinal side ioor strip 18 and a plurality of pivoted drop bottom doors each of which is designated generally by the reference character A. The number of the floor doors will vary in accordance with the requirements of the different railroads but generally there will be four on each side of the Car. Only one of such doors is illustrated in detail in the drawings, it being deemed unnecessary to show or describe any of the others, inasmuch as it will be understood that the arrangement is similar for each door.

Each of the doors A, is preferably composed of a plurality of longitudinally extending sliiplapped planks 19-19 bound together by U-shaped binding plates 20-20 at each end of the door and further secured by a top strip 2l located centrally, as best shown in Figure 3. On the under side, each door A is preferably braced or strengthened by novel combined braces and hinge straps indicate-d generally by the reference character B.

Each of said combined braces and hinge straps B .is preferably inade of an angle iron which can be obtained from stock,tlie same being secured to the under side of the door with one fiange thereof located'at the top as indicatedK at 22 and secured to the under face of the door and with the other right angular flange 23 extending -vertically downwardly. At the inner or hinge edge of the door, the upper iiange 22 is extended bevond the door edge and bent downwardly for a short distance as indicated at 22a, thence bent in the form of a circle, as iiidicated at 22 around a hinge pin 24. the remainder of the iiange being thence doubled back against the section 22fL as indicated at 22c and thence horizontally beneath the door as indicated at 22d. The other flange 23 is extended up to the hinge pin and beveled off as indicated at 23' so that a strong brace is supplied for the flange sections 22i1 and 22c right up to the hinge or pivotal connection. The hinge pins 24 Vare mounted in hinge rectl below the free edge of the door, the debutts 25 which are riveted in the upper corners of the correspronding channel center silly 10, asshownin igure 2.

At the free edges of the door, the braces B are extended beyond the edge of the door and downwardl bent fora slight distance as indicated at 'At a point approximately dipen ing flange 23 of the-brace is bent out of themain plane of said flange 23 in a more or less horizontal direction as ,indicated at; 23.b so that, looking at the end of the .brace B it has the form more lor less of a channel cross section, as clearly indicated in Figure 4. Theflange section 23b is preferably curved on a radius about acenter which is located above the door so as to cooperate with a correspondingly curved supporting shoulder 26 on a pivoted latch 27 The latter is pivotally supported on the outer face of the car side wall as indicatedat 28 in a casting 29. The y forcibly elevate the door to fully closed posiv tion. By forming the fbrace B at its outer end as above described, it will be observed that I obtain a very strong section, inasmuch as I retain a part of the vertical web 23 Ias a compression element in sustaining the load on the door and thus eliminate or at least minimize tendency of the flange section 23b to give or bend under load as it might otherwise do. In actual practice, there will preferably be two of the combined braces and hinge straps B for each door and4 two corresponding pivoted gravityv latches cooperablewith the outer extended ends thereof.

In the gondola car shown'l in Figures 1, 2 and 3,'thesame is of the type known as composite and the doors are relatively wide, extending substantially from the .center sill to the plane of the side wall. With doors of such width, it is inadvisable to allow them to fall to a depending vertical position on account of interference with the rail and consequently I have' shown stop plates 32 secured to the needle beams 11 and 12 which willlimit the opening movement ofthe doors. Preferably also I employ a longitudinally extending cover yplate 33 secured to the cen- .ter plank 17 and extended a slight distance beyond the free edge. thereof over the joint -between the door and the plank toprevent as much as possible, any of the load getting in the cracks. A similar cover plate 34 may be employed along --the free -edges of the doors, as clearly' shown in Figure 2J "tance toward the side wall of the car.

floor doors are indicated at A', the same dola car therein shown isof the al1 steel type, the same having center sills 110, transverse needle beams 111 and 112, side wall 113, sidestakes 114, angle side sills 116, and -longitudinally extending center coverA plate 117 over the center sills. In this form of gondola car, the width of, the doors is ymade considerably vless than in the composite type, there being a floor section 40 extending from the center sill about one-third of the dis- The being relatively narrow and having their free edges engaging beneath the horizon-l tally extending flange of the side sill 116, as best shown in Figure 6. Each of the doors A is preferably provided with a combined brace and hinge strap B2 formed in the same manner as the corresponding door member B, heretofore described. In this connection, it will be observed from examination of Figure 6, that the outer end B3 of each brace B2 is defiected downwardly a much greater extent than in the construction heretofore described in order to pass below the side wall of the car, which is extended below the level of the fioor. outer end of the brace B2 is formed in the same manner as the outer end of the braces B and similar latches are adapted to cooperate therewith and need not be redescribed.

.beam to needle beam and has secured thereto at each end, complementary hinge butt castings C. Said castings C are made right and left and it will only be necessary to describe one of them in detail.

Referring more particularly to Figures 6, 7 and 8, each of Asaid castings 'C is formed at its end with a flange 44 extending in a vertical plane transversely of the car and adapted to b e directly riveted to the correspending needle beam 111 or 112, it being understood that said fiange 44 extends across the end of the Z-bar 41. Each casting C is further provided with a horizontally extending iiange 45 located beneath and secured to the bottom flange 43 fof the Z-bar and with a further vertical flange 46 overlapping and riveted to the web of the Z-bar.

At the inner end of each casting C, that is` the end removed Afrom the corresponding needle beam to which it is secured at its other end, each casting C is provided with a pair.

The

ico

of spaced vertical flanges 47-47 which are extended upwardly to a point beneath the Z-bar flange 42 and free edge of the Hoor plate 40, as best indicated in Figures 6 and T. Said spaced fianges 47 are suitably reinforced by edge ribs 46a and together provide pivotal supports :for a hinge pin 126.

.Each of the doors A, vas previously described, is preferabfly made of sheet metal and to insure the necessary strength, each door has a depending flange around each edge thereof. Along its hinge edge, said flange, indicated at 48, is slightly indented as indicated at 48a to clear the free edge of the Z-bar liange 42 and thence is curved on a radius concentric with the hinge pins 126. When the door is in closed. position, as shown in Figure 6, it is evident that a comparatively tight seal is obtained between the hinge edge of the door and the floor plate 40 and furthermore, as the door swings to its fully open position, the curved ange 48 and Z-bar flange 42 will maintain their tangential relation, thus preventing any of the load getting in between the door and fixed part of the car andinsuring easy closing of the door. J l

In the arrangement shown in Figures 5 to 8, on account of the door being comparatively narrow, the same may be allowed to swing to a depending vertical position as-indic-ated bydotted lines in Figure 6, the door clearing the rail, a portion of the latter being indicated conventionally. This allows of 100% door opening and easy discharge as will be understood by those skilled in the art.

One advantage of the combined floor brace and hinge butt structure just described resides in the fact that the castings C may be made of standard patterns and combined with a Z-bar for any car, regardless of the distance between the needle beams or diaphragme, inasmuch as the Z-bar may obviously be cut to any desired length so that the castings C can always be riveted directly to the needle beams. This 'is of considerable advantage over bracesof the ordinary cast type which require separate patterns for cars having different spacing between needle beams.
